..............If you go in from windward you're swinging the bow downwind already in the turn, and the wind will exaggerate and increase the bow's blowing off downwind... IMO............

This can be true unless, when you place your quarter at the outside windward piling, you warp around the piling with a line to the bow and stern. This gives you absolute control of the rate at which your bow turns off the wind once you have partially entered the slip. I would repeat, though, that this strategy does not work if the adjacent boats extend beyond the end pilings of the slips.
